` To aZjZ whom t may concern:

Beit knownthat I, ARTHUR W. {Brasca-a citizen' fof the United States, residingl at Qinaha, .in `the county ofxDouglas.1 and Ititafte j of Nebraska, AV,have inventedy ertainne,wA :and

Zoiital planefwhicli Usliaped `members are ated by the ntrain for `retfurning'g'"the Llil-shaped moved to ,a vertical position through' `mechanisrnactuate'd by a train for preventing-ve 4liicles` and the `like from' crossing 'the track.

A further obj ect Ais to providemean'sfactumembers to horizontal inoperative position lights on the U-shaped members so they can be easily observed at night.

A further object is to provide a lever means whereby the gates can be manually operated if desired.

With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing Figure 1 is a top plan view of a conventional form of railway crossing, showing the device applied thereto.

Figure 2 is a transverse sectional view taken on line 2-2 of Figure 1.

Figure 3 is a perspective view of the supporting posts for one end of one of the shafts and the securing means.

Referring to the drawing, the numeral 1 designates a conventional form of railway and 2 a roadway crossing said railway at a right angle. Disposed adjacent opposite sides of the railway 1 are spaced ties 3, to the outer ties of which elongated shafts 4 are connected and rotatably mounted in bearings 5, whereby said shafts may rotate. Although ties are described for use as a base for the shafts, it is to be understood that any other suitable foundation may be used.

Shafts 4 may be of any length desired ,and

extend beyond'theoppositesidesof the' roadway -2, and ,have oneof theiry ends :provided with i'iriwardly extending horizontallydisends provided with pins 7 whiclrextend ftl'irou-g'li elongated slots 8 initransv'erse-ly disl:posed'roclr Llevers' 9,1which levers are pivote *ally mounted at"101adj acent @the undeimsides f of therails 1.1 of the rafi'lwlay`,'anil :haue their innerends' terminating" lin upwardly and finl 'wa'rdlyextending arms 12,'wl1ich terminate adj acentthelinner sides olfithe rails .11,where Ythe cars of airailroad" train or engine, .and will be forced downwardly, `thereby rocking the levers 10 irpwardliywa't theimrrfoirter fend andv moving fthe' arms i6 to i a4 vertical. position substantially i ninety ,degrees l Ehe Pellafte n l whe'rethey cross the .roa'dway12 .are provided afterfpassingthe crossing. Also to provide t with' Ushap'ediportions 113,3 .which portions are normally horizontally disposed and which form a barrier for vehicles crossing the railway when moved to a vertical position upon the approach of a train and a partial rotation ofthe shafts 4 when the wheel ianges ofthe train depress the arms 12 of the levers 9. When the U-shaped members 13 are in raised position they form a barrier for preventing vehicles from crossing the track, however for night purposesJthe U- shaped members 13 are provided with lamps 14 which will be plainly visible to operators of vehicles approaching the crossing.

The ends 15 of the shafts 4 are rotatably mounted in posts 16, and are provided with levers 17, which levers when the shafts are automatically rotated by the train approaching the crossing moves upwardly and outwardly and vinto engagementwith the hooks 18 carried by the posts 16, thereby limiting the rotation of the shafts. Levers 17 also form means whereby the shafts may be manually operated if so desired, thereby allowing the barriers to be manually moved to operative or inoperative positions. The shafts 4 outside of the posts 16 are provided with downwardly extending arms 19, which' arms have pivotally connected thereto at 2O inwardly extending rods 21, which rods extend beneath the rails 11 and are pivotally connected at 21 to the arms 23 of a horizontally pvoted member 24, therefore it will be seen that when the parts are in the normal position shown in Figure 1 an angularly -pin 26 and 1move thepivoted member 24 vto normal position shown in Figure l, and -rock the shafts .land the U-shaped memcrossing. means 1s provided whereby barriers may be disposed member 25 carried by the last car of a train would pass the restoringpin 26 carried by one of the arms 23, however after "the shafts have been rotated ninety degrees in the mannerset forth above vthe pin 26 will be in a position ninety degreesfroml that shown in Figure 1, and consequently in the path of the angulafrly disposed member 25 carried by the last car of the train, therefore the member 25 will engage the bers 13 to horizontal4 position as shown in Figure 1.

From the above it will be seenthat a train operated barrier isA provided for railroad crossings, which barrier will be movedv to operative position by a train upon approaching the crossing and will be restored to normal positionbyv the train after passing the It will also be seen that manual operated by hand if desired.

The barrier elements are ymaintainedjin operative positions by the positioning of the U-shaped members 13 in vertical positions which vis insuredvrby the limitingrarms 17 Vengaging the hooks 18. It is to beundeI'-, stood'the device is.- of considerabler length,

consequently the barrier elements will be moved `to operative position by the engagement of the wheels of the car or train approaching the crossing with the members 12. The invention havin@ been set forth what is Aclaimed as new and useful is The combination with a railway, of railwayv crossing barriers, said barriers comprising longitudinally disposed rockable shafts Y the rods are pivotally connected, a vertically disposed pin carried by said horizontally pivoted member, said pin being adapted to be engaged by a member carried by; a train-i for restoring the U-shaped members to normal horizontal position after the train has passed a crossing.

In testimony whereof I aiiiX my signature.
